Abstract
Ground-based high-resolution FTIR spectrometers are used within the NDACC (Network for the Detection of Atmospheric Composition Change) for measuring the concentration of trace gases in the atmosphere. Fits of atmospheric spectra using the methane HITRAN 2012 line list indicate residual deficiencies of the spectroscopic data in the MIR region between 2400 cm-1 and 3000 cm-1 used by NDACC for the retrieval of CH4 profiles. The aim of this work is to further improve these parameters based on laboratory spectra. Target parameters are the line position and the line intensity as well as the air-broadening and the air pressure induced shift parameter. Moreover, speed dependence and line mixing effects were taken into account.
